jbs Posted September 14, 2010 Share Posted September 14, 2010 Big Sail, and lot's of wind or a very light right boot and drive it like your grand father would-very gently! Quote Link to comment Share on other sites More sharing options...
gazelle Posted September 14, 2010 Share Posted September 14, 2010 Have a look herefor fuel economy for Defenders for various engines. If you want 30mpg you will probably need to buy a new car! Quote Link to comment Share on other sites More sharing options...
landroversforever Posted September 14, 2010 Share Posted September 14, 2010 Drive like an angel! Seriously though, sensible sized tyres, light right foot, loose the extra weight from the car will help Quote Link to comment Share on other sites More sharing options...
Top90 Posted September 14, 2010 Share Posted September 14, 2010 If you can get 30mpg from a 2.5NA you'll be so bored driving like that that you'll not want to drive much, which will save even more fuel. Better to live with a few mpg less or fit a Tdi. Quote Link to comment Share on other sites More sharing options...
Maverik Posted September 14, 2010 Share Posted September 14, 2010 Take the roof off and fold the windscreen down - but buy some goggles, I was amazed at how nippy mine was! In all seriousness, I think weight loss is your friend. Quote Link to comment Share on other sites More sharing options...
lrfarmer Posted September 14, 2010 Share Posted September 14, 2010 i cant get my 200tdi to do much more than 28MPG on 205/80/16 road tyres but good luck if you can Quote Link to comment Share on other sites More sharing options...
Aragorn Posted September 14, 2010 Share Posted September 14, 2010 I'm sure LRO did an article on this a few years ago. As folk have said though, road tyres properly inflated, a well serviced engine so its running as efficiently as possible, then onto the weight loss. Remove any bolt on kit like roof racks and snorkels, ditch all unneccesary carp from the back such as tools/spares/etc Also worth checking to ensure none of the brakes are binding causing drag and that all the wheel bearings etc are in good condition. If your still not there, start removing body panels Also depends where your driving it. It'll be much easier to attain 30mpg sitting at 56mph on the inside lane of the M6 behind a 44tonner than it will driving round the local lanes.

Off Road Toad Posted September 14, 2010 Share Posted September 14, 2010 I've just removed my roll cage from my 4.6 90" and was amazed to find driving back from peterborough to surrey i used 1/4 of a tank LESS fuel than i did going up with the cage on! so - weight and drag is your enemy Steve Quote Link to comment Share on other sites More sharing options...
Retroanaconda Posted September 14, 2010 Share Posted September 14, 2010 That's because it's downhill Steve I'd like to see 30mpg from my 110 when it's done, at the moment it's doing 26mpg with 265 ATs, so I'm hoping that when I have it sitting on road tyres at the correct pressures, and I have serviced the engine/gearboxes, I might be able to get close to 30mpg. If driven conservatively! It did 24mpg on a run to West Hampshire and back, but it was loaded with five people and the back literally full of gear Quote Link to comment Share on other sites More sharing options...
Flatout Posted September 14, 2010 Share Posted September 14, 2010 Change your driving style, drive like a truck driver lift off trottle well before a corner or lights. This saved me about 2mpg and then i invested in a K&N air filter this also got me about 3mpg. All in all it has taken my td5 up to 32mpg.

nicks90 Posted September 14, 2010 Share Posted September 14, 2010 leave it at home and buy a small diesel eurobox and get 55mpg. depending on the mileage you do it'll pay for itself in about 1 year.... otherwise, as others have said. drive like a saint, remove all the weight you can and airflow problems like cages and snorkels, use road tyres, give the drive train a bloody good service. ( * ) ( * ) interestingly, the cost of rebuilding all the brakes and hubs etc and nice fancy oils will probably take several years to recoup on the fuel you save....

It's vehicle with the aerodynamics of a brick. That, along with quite a bit of inbuilt transmission drag and other factors coupled to an elderly power-plant means you are never going to achieve a great deal of fuel efficiency and get anywhere reasonably quickly. Stick to proper servicing and lubricants and learn to read the road and use the gears / brakes efficiently. Drive as though you have an eggshell between your foot and the accelerator and a shallow bowl of eggs suspended over you head Quote Link to comment Share on other sites More sharing options...

Yostumpy Posted September 14, 2010 Share Posted September 14, 2010 Well my 300 110 does 28mpg, butI worked out the equivalent mpg, as I'm running on 50% veg, at 79ppl for veg ( usual price), and 115 for dino, it equates to 33mpg, BUT at the special deal I got thro tesco's with a BOGOF deal, at 42ppl it works out to a stagering 41mpg!!, only got about 200 ltrs left now tho!

RustyNissanPrairie Posted September 14, 2010 Share Posted September 14, 2010 take the cooling fan off, a 2.5na dosnt need one if the rad/cooling system is in good order. free's up a few HP. Quote Link to comment Share on other sites More sharing options...
